Well, aside from the imperative to euthanise the least happy regardless of their absolute happiness, I guess :-).
And making most individual actions normally called moral or immoral difficult to justify or condemn except that they might indirectly affect the least happy person.
And then there's the weird idea that my local actions may have moral weight depending on the arbitrary existence of an unhappy person in a distant country.

All seems pretty bizarre to me.
